Embodiment Construction
[0046] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0047] According to an embodiment of the present invention, such as figure 1 , figure 2 and image 3 As shown, a method for ultra-short-term prediction of photovoltaic power generation based on all-sky imaging data is provided.
[0048] The ultra-short-term prediction method of photovoltaic power generation based on all-sky imaging data in this embodiment mainly includes the following steps:
[0049] Step 1: Binarize cloud image data.
[0050] According to the pre-set threshold, the cloud time series images captured by the all-sky imager are binarized by digital image processing technology.
[0051] Step 2: Cloud detection and labeling.
[0052] For the proces...
